Summary
An unusual case of automatic rhythm originating from a Mahaim pathway presented as parasystole. This parasystolic rhythm initiated tachycardia, leading to incessant tachycardia and tachycardia-induced cardiomyopathy.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Arrhythmias
Background:
- Mahaim pathways are accessory pathways that can exhibit automaticity.
- Automaticity in Mahaim pathways can manifest spontaneously or during procedures like radiofrequency ablation.
Purpose of the Study:
- To describe an unusual case of an automatic rhythm originating from a Mahaim pathway.
- To highlight the presentation of this automatic rhythm as parasystole.
- To report the consequences of this parasystolic rhythm, including tachycardia initiation and cardiomyopathy.
Main Methods:
- Case report detailing an unusual cardiac arrhythmia.
- Clinical presentation and electrophysiological findings analysis.
- Review of literature on Mahaim pathway automaticity and parasystole.
Main Results:
- An automatic rhythm from a Mahaim pathway was observed presenting as parasystole.
- The parasystolic beats were identified as the trigger for tachycardia.
- The patient presented with incessant tachycardia and subsequent tachycardia-induced cardiomyopathy.
Conclusions:
- Mahaim pathway automaticity can manifest as parasystole.
- Parasystole from a Mahaim pathway can lead to incessant tachycardia and cardiomyopathy.
- This case expands the understanding of Mahaim pathway arrhythmogenesis.

13.1K
Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

01:20Conduction System of the Heart
6.0K
The cardiac conduction system produces and transmits electrical impulses that prompt myocardial contraction, ensuring efficient heart function. This intricate system ensures that the heart beats in a coordinated and efficient manner, beginning with the atria and then the ventricles. The conduction system optimizes cardiac output by maintaining this precise sequence, which is crucial for adequate blood circulation.

01:28Mechanism of Cardiac Arrhythmias
2.7K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

01:19Electrophysiology of Normal Cardiac Rhythm
7.8K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

01:13The Cardiac Cycle
77.2K
The heart beats rhythmically in a sequence called the cardiac cycle—a rapid coordination of contraction (systole) and relaxation (diastole).
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
